Above the cups 15 the nipple has a plurality of series of upwardly and outwardly directed fluid discharge passageways 2l) disposed to direct the pumped fluid upwardly against the barrel walls above the traveling valve to wash said walls clean. Attached to the lower end of the body 6 there is the bottom tubular nipple 21 whose outside diameter is some what less than the inside diameter of the barrel so as not to contact therewith. On the upper end of the nipple 21 there is an annular valve seat 22- which is controlled by the upwardly opening ball valve 21- This valve 23 is located in an enlarged chamber 24, in the lower end ot said body7 6 and is confined, in its upward movement by the cross rod 25. T he upper portion of the nipple 21 is hexagonal to receive a wrench and the nipple 21 is reduced beneath this portion forming an annular downwardly facing shoulder 26 against which the upper one of a series of cup rings 27, ahuts. These cup rings are arranged onthe reduced portion of the nipple 21 and there open ends face downwardly and they are spaced apart by the spacer rings 28. These rings 27, 28 are held in assembled relation against the shoulder S26 by the ring nut 29 which is threaded on the lower end of the nipple 21 and abuts the lower spacer ring 28.

In operation on upward movement of the traveling valve the ball valves 9 and 2l, will he closed and the standing valve will open and the fluid from beneath will be drawn into the working barrel. The cup rings 15, upon such upward movement will sweep the grit and sand from the inside wall of said working barrel so that the traveling valve body (3 will not be cut away thereby. Upon downward movement of the traveling valve the standingT valve will close and the ball valves 9 and Q3 will be lifted and the fluid being pumped will pass above the traveling valve. Said Huid will be discharged in streams through the passageways 20 against the walls of the barrel 1 and will wash the sand and grit otl'the walls of said barrel in advance of the cup rings 15. The cups 27, upon downward movement, will clean the inner walls. of the barrel 1 of grit and sand to prevent the body from being worn thereby.

The nipples 7 and 21 are made ot corrosive material but in case they become corroded Aand pitted by the acid in the tluid they will not score or wear the working barrel inasmuch as they are not in contact therewith.

It is obvious that mechanical changes may be made and equivalents substituted for the parts shown and the right is reserved to make such changes and substitutions as may be 'found desirable and such as may be comprehended within the scope of the appended claims.

W'hat we Claim is 1. A traveling valve including a tubular body, a tubular valve casing attached to the upper end of said body, a valve seat in the lower end of the. casing, an upwardly opening valve controlling said seat, a de )ending tubular thimble within the casin an spaced above said valve Whose lower end is provided with a valve seat, said thimble having a lateral port above said lower end, a tubular nipple attached to the upper end of said cage whose upper end is reduced forming a connection for a sucker rod, a series of cup rings on said nipple Whose open ends are directed upwardly and which are spaced apart, means on the'nipple between which said cup rings` are clamped, said nipple being provided with a series of upwardly and outwardly directed fluid discharge passageways above said cup rings, a bottom tubular nipple attached to the lower end of said body, a valve seat at the upper end of said bottom nipple, an upwardly opening valve controlling said last mentioned valve seat, a series of cup rings around said bottom nipple with their open ends facing dmvnwardly and means for clamping said cup rings of said bottom nipple.

2. A traveling valve including a tubular body, a tubular valve c asing attached to the upper end of said body and whose outside diameter is lessthan that of said body, a valve seat in the lower end of the easing, an upwardly opening valve controlling said seat, a depending tubular thimble within the cas ing and spaced above said valve whose lower end is provided with a valve seat, said thim-l ble having a lateral port above said lower end, a tubular nipple attached to the upper end of said cage whose upper end is reduced forming a connection for a sucker rod, a series of cup rings on said nipple whose open ends are directed upwardly and which are spaced apart, means on the nipple between which said cup rings are clamped, a metallic reinforcing ring within the upper cup ring. said mpple being provided with aV series of upwardly and outwardly directed fluid discharge passageways above said cup rings, a bottom tubular nipple attached to the lower end of said body whose outside diameter is less than that of such body, a. "alve4 seat at the upper end of said bottom nipple, an npwardly opening valve controlling said last mentioned valve seat, a series of cupa-ings around said bottom nipple with their open ends facing downwardly, and means f or clamping said rings of said bot-tom nipple.

In testimony whereof we have signed our names to this specification.
